摘　　要：云南玉溪大红山铁矿于2013年4月被国土资源部授予"国家级绿色矿山试点单位",为了检验绿色矿山推进效果,更好地带动云南省其他矿山企业建设绿色矿山,项目组于2016年丰水期(8月)针对大红山矿区周边水体进行调查,对矿山企业进行调研,用单因子评价法和内梅罗指数法进行评价,结果表明所有采样点的水质都为优良,研究区大致的水质情况通过该评价体现出来。对比2008年数据,从评价结果来看,Hg、Cd、Se、Ag、Pb均低于检出限,未见任何超标样点。Cu、Zn、As有检出但均低于国家Ⅰ类标准,43.75%的采样点中Fe的浓度低于国家Ⅰ类标准限制,未见超标,有一个样点属于国家Ⅱ类标准,其余50%的样点低于国家Ⅳ类标准,可见通过绿色矿山建设,循环经济工作取得了显著成果。Iron mine in Dahong Mountain in Yuxi,Yunnan was awarded the ＂ national green mining pilot unit＂ by the ministryof land and resources in April,2013. In order to test the green mining effect,and drive the other mining enterprises in Yunnan province building green mines. The water bodies around？ iron mine in Dahong mountain during wet season（ August） in2016 was investigated,and the mining enterprises were surveyed. Water quality was evaluated by Single factor evaluation method and Nemerow Index method,the result showed that water quality of all sample were good,water quality of the studied area is roughly reflected by the evaluation. Compare to the data in 2008,from the evaluation results,the concentration of Hg,Cd,Se,Ag,Pb is below the detection limit,the concentration of Cu,Zn and As were detected but were all below the national standard,The concentration of Fe in 43. 75% of all the samples were below the national standard limit I,and in one sample is below the national standard limit II,other 50% of the samples were below the national standard limit IV. Heavy metal pollution is reduced obviously. Circular economy work has made remarkable achievements through the green mine construction.
